Akira came to visit her new friend's house for the first time. There, I met a mother Eri who was too beautiful. Unlike her mother, Akira fell in love with her youthful and gentle collar at first sight, but she saw a shocking sight that shattered her faint love. Eri brought a stranger into the room and engaged in unfaithful acts. Akira is angry at the appearance of Eri who is mushy at the cock of a man who is not her husband while her son and his friend are in the next room.
